Summary: Mesa demos should use XDisplayName when printing errors
Product: Mesa
Version: 6.5
Platform: All
OS/Version: Solaris
Status: NEW
Severity: normal
Priority: P2
Component: Demos
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
When printing errors such as "Can't open display" many of the Mesa demos use
code such as:
printf("Error: couldn't open display %s\n", dpyName);
These messages should instead use XDisplayName, both to substitute in $DISPLAY
when using that because -display wasn't passed, and to ensure that if neither
was set, the result returns a string of "" instead of a NULL pointer, so they
don't segfault on OS'es like Solaris which segfault on printf("%s", NULL).
Patch to cleanup the demos follows.
